My costum story keeps crashing after some time?

[Melaara]

I did not mess with some files, neither did I do an update. But it is true that there might be something wrong with the brute, because at the and I added one with a trigger effect. I'm not sure why it keeps crashing on exactly this one, because I already have a brute right at the beginning, but with no trigger effect... Would be stupid if I could not spawn a brute that way.

However, here's my hps file.

Thank you for your help, everybody.
